Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true. The description adds useful behavioral context beyond that: it returns CLI setup, how-it-works, skill file, and remote MCP hops, and explicitly states that task text is discarded. There is no contradiction with the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the action and resource, then lists outputs compactly. Every phrase earns its place, with no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

In the absence of an output schema, the description does explain the return content at a useful level (CLI setup, how-it-works, skill file, remote MCP hops). The parameter schema handles the remaining detail. A small gap is the unexplained term 'Monid' and no explicit statement of which parameters to populate, but overall it is sufficient for a discovery tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with each of the seven parameters having its own description in the input schema. The tool description itself adds no parameter-specific meaning beyond the general note that task text is discarded, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Find') and names a distinct resource ('public pay-per-call tool gateway (Monid)'). It also lists concrete outputs: CLI setup, how-it-works, skill file, and remote MCP hops. It does not explicitly contrast with sibling tools like web-fetch or fetch-status, but the discovery/gateway focus is clear enough.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is implied: use this when you need a Monid pay-per-call tool gateway and its setup/skill files. However, the description gives no explicit when-not-to-use guidance or alternatives, even though several siblings are plausible alternates for fetching or validating URLs.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
